Soluzione - Long subtraction
0,14
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths |
| 1 | , | 4 | 1 | |
| - | 1 | , | 2 | 7 |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (1) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (11).
| Place value | ones | . | tenths | hundredths |
| 3 | 11 | |||
| 1 | , | 4 | 1 | |
| - | 1 | , | 2 | 7 |
| , |
Subtract the numbers in the hundredths column from the top number:
11-7=4
| Place value | ones | . | tenths | hundredths |
| 3 | 11 | |||
| 1 | , | 4 | 1 | |
| - | 1 | , | 2 | 7 |
| , | 4 |
Subtract the numbers in the tenths column from the top number:
3-2=1
| Place value | ones | . | tenths | hundredths |
| 3 | 11 | |||
| 1 | , | 4 | 1 | |
| - | 1 | , | 2 | 7 |
| , | 1 | 4 |
Subtract the numbers in the ones column from the top number:
1-1=0
| Place value | ones | . | tenths | hundredths |
| 3 | 11 | |||
| 1 | , | 4 | 1 | |
| - | 1 | , | 2 | 7 |
| 0 | , | 1 | 4 |
The solution is: 0,14
